TRANSFER AND HINGE FOR EVAPORATING-PANS.

SPECIFICATION forming part of Letters Patent No. 694,874, dated March 4,1902.

' Application filed April 3, 1 901. $erial No. 54,157. (No model.)

To aZ'Z lull/0772 it may concern:

Belt known that I, GALUSHA A. KING, a cit izen of the UnitedStates,residing at Linesville, in the county of Crawford and State ofPennsylvania, have invented certain new and useful Improvements in aCombined Transfer and Hinge for Evaporating-Pans; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates particularly tothat class ofevaporator-s'employed in the manufacture of sugar and syrup, and hasspecial reference to an improvement in the means which are utilized tomaintain communication between the entire series of pans in order thatthe process of evaporation may be properly carried out.

To this end theinvention contemplates an improved transfer orcirculating connection between adjoining evaporating-pans comprisingmeans for not only permitting circulation from one pan to the other atthe proper point, but which also acts in the capacity of a hinge for thepans, whereby the pans can be individually raised and lowered, as isnecessary in the handling thereof for emptying and other purposes.

In such transfers as have heretofore been used ground joints andscrew-joints have largely been utilized in effecting a connectionbetween the transfer members; but an objection to the ground jointresides in the fact that joints of this character occasionally stickwhen a pan is raised, and thereby wrench or break ahole in the same,while with the screwjoint it is verydiflicult to construct the same, soas to obviate leakage. The presentinvention contemplates an improvedconstruction involving a packed joint so arranged as to entirely obviatethe objections to the ground and screw joints,besides permitting thetransfer to constitute an easy and perfect acting hinge for the pans.

lVith these and other objects in vie W,which will more readily appearasthe nature of the invention is better understood, the same consists inthe novel construction, combination,

\Vhile the invention is necessarily suscep- 'transferand hingeconnecting the same. Fig.

3 is a sectionalv view on the line 3 3 of Fig. 2 of the drawings. 7

Like numerals of reference designate corresponding parts in the severalfigures of the drawings.

For the purpose of illustrating the utility and application of theinvention there is shown in the drawings a sugar-evaporator embodying inits general organization a furnace 1, having the usual elongatedflue 2and supporting withinthe top portion thereof the series ofevaporating-pans 3, which preserve 'the same general relation andarrangement as the evaporating-pans of the ordinary types ofsugar-evaporators- As already explained, the present inventioncontemplates specially an improved construction of transfer orcirculating connection between adjoining pans, which will alsoconstitute a hinge for such pans, so in the construction of theevaporator the pans 3 are seated within the top portion of the furnaceand its line, so as to be capable of beingindividually raised andlowered. In order to make suitable provision for the proper hiuging ofthe outside corners of the terminal orend pans of the series, suchterminal or end pans have fitted to their outside corners at one endthereof trunnions or pintles 4;, loosely engaging in bearingbrackets 5,fitted upon the furnace contiguone to the trunnions or pintles 4, asplainly shown in Fig. 1 of the drawings. The combined transfer and hingeis necessarily used between the adjoining pans and is arranged atthecorners of the pans contiguous to one end thereof, also inlongitudinal alinement with'the terminal trunnions or pintles at inorder that the hinges for all of the pans will be uniformly arranged atone side of the evaporator, thus facilitating the emptying of the pans.

. jacent pan.

Referring particularly to the construction of each of the combinedtransfers and hinges,

the same comprises separate tubular mem-' bers 6 and 7, respectively,telescoping one within the other, so as to, provide a continuouspassage-way therethrough, while at the same time permitting one memberto turn on the other as an axis when the pans are raised and lowered, itof course being understood that one member of the transfer and hinge iscarried by one evaporating-pan, while the other member is carried by thedirectly ad- The tubular member 6 of the combined transfer and hinge iselongated and extends practically across the space between two adjoiningpans, and therefore constitutes the main supporting portion of thedevice, so the same may be properly termed the journal member, while theother member 7 constitutes the sleeve member fitting over the portion ofthe said journal member 6 between the pans.

Each of the members 6 and 7 of the combined transfer and binge isprovided at its inner end within the pan, to which it is attached with asecuring-flange 8. The securing-flanges 8 of the said members 6 and 7are designed to be soldered or otherwise rigidly fastened to the innersides of the pans, while the shanks or tubular portions of the membersextend through side openings 9, formed in the pan-walls, and to providefor positioning the transfer members as closely as possible to thebottom corners of the pans contiguous to one end of such pans theflanges 8 are preferably of a sector shape, the same having truncatedangular side portions 10 fitting in the corners of the pans, as plainlyshown in Fig. 3 of the drawings. When the parts are assembled, themember 6, as already explained, extends practically across the spacebetween two adjoining pans and fits inside of the short neck portion 11of the sleeve memher 7, and said neck portion-11 exterior to the pan isexteriorly threaded to receive thereon the interiorly-threaded collarportion 12 of an adjustable packing-nut 13, provided with aninwardly-projecting joint flange 14, closely fitting upon the exteriorsurface of the tubular journal member 6. Within the nut 13 and upon theexterior of the journal member 6 is arranged suitable packing 15 ofcandle-wicking or equivalent material, which is designed to becompressed between the jointfiange 14 and the outer end of thesleeve-neck 11. This construction provides a packed joint between theadjoining pans, and by reason of the adjustability of the nut 13 thejoint between the members or sections can be made perfectly tight,besides producing an easy and perfect-acting hinge upon which the panscan be individually raised and lowered. Furthermore, the location of thenut 13 intermediate of the two pans renders the same easily accessible.

From the foregoing it is thought that the construction, operation, andmany advantages of the herein-described transfer and hinge will bereadily apparent without further description, and it will be understoodthat changes in the form, proportion, and minor details of constructionmay be resorted to without departing from the spirit or scope of theinvention.

Having thus described the invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In an evaporator, the combination with the series ofevaporating-pans, of a combined transferand hinge arranged wholly insideof the space between adjacent pans and extending across such space orinterval, said combined transfer and binge providing a straightawaypassage from pan to pan and comprising a tubular elongated journalmemberhaving a flanged end fitted to one pan, a tubular sleeve memberalso having a flanged end fitted to the corresponding side of theadjoining pan, and packing arranged about the journal member at theouter end of the sleeve member.

2. In an evaporator, the combination with the evaporating-pans, of acombined transfer and binge comprising a tubular elongated journalmember fitted to one pan, a tubular sleeve member fitted to an adjoiningpan and receiving therein an end portion of the jour nal member, saidsleeve member having a threaded portion, and an adjustable packingnutclosely fitting the exterior of the sleeve member and having a threadedcollar engaging the neck of said sleeve, and packing arranged within thecollar of the nut and against the outer end of the sleeve member.

In testimony whereof I affix my signature in presence of two witnesses.
